A curved optic structure includes an optic film, a polarizer and a liquid crystal compensation film. The optic film includes a light incident side and a light exit side. The optic film has a curved surface on the light exit side. The polarizer is conformally attached on the curved surface. The liquid crystal compensation film is disposed at the light exit side of the optic film. The polarizer is located between the optic film and the liquid crystal compensation film. The liquid crystal compensation film includes a liquid crystal layer and a power supply. The liquid crystal layer includes a plurality of liquid crystals inside. The power supply is connected to a first side surface and an opposite second side surface of the liquid crystal layer.
